In the STIHL KombiSystem a number of
different KombiEngines and KombiTools
can be combined to produce a power
tool. In this instruction manual the
functional unit formed by the
KombiEngine and KombiTool is referred
to as the power tool.
Therefore, the separate instruction
manuals for the KombiEngine and

Guide to Using this Manual Safety Precautions and
Working Techniques
Some special safety pre-
cautions must be
observed to reduce the
risk of personal injury
when operating this
power tool because of the
very high speed of its cut-
ting attachment.
Always read and and
make sure you under-
stand both instruction
manuals (KombiEngine
and KombiTool) before
using your power tool for
the first time and keep
them in a safe place for
future reference. Non-
observance of the safety
precautions may result in
serious or even fatal
injury.

are technically identical. If you have any
questions in this respect, consult a
servicing dealer.
Use only high quality tools and
accessories in order to avoid the risk of
accidents and damage to the machine.
STIHL recommends the use of genuine
STIHL tools and accessories. They are
specifically designed to match the
product and meet your performance
requirements.
The deflector on this power tool cannot
protect the operator from all objects
thrown by the cutting attachment
(stones, glass, wire, etc.). Such objects
may ricochet and then hit the operator.
Never attempt to modify your machine in
any way since this may increase the risk
of personal injury. STIHL excludes all
liability for personal injury and damage
to property caused while using
unauthorized attachments.
Do not use a pressure washer to clean
the unit. The solid jet of water may
damage parts of the unit.
Clothing and Equipment
Wear proper protective clothing and
equipment.
Avoid clothing that could get caught on
branches or brush or moving parts of the
machine. Do not wear a scarf, necktie or
jewelry. Tie up and confine long hair
(e.g. with a hair net, cap, hard hat, etc.).
WARNING
Wear a face shield and make sure it is a
good fit. A face shield alone does not
provide adequate eye protection.
Wear hearing protection, e.g. earplugs
or ear muffs.
STIHL offers a comprehensive range of
personal protective clothing and
equipment.
Transporting the Power Tool
Always turn off the engine.
Carry the unit properly balanced by the
drive tube or loop handle.
Transporting by vehicle: Properly secure
your power tool to prevent turnover, fuel
spillage and damage.
Before Starting
Check that your power tool is properly
assembled and in good condition – refer
to appropriate chapters in the
KombiEngine and KombiTool instruction
manuals.
– Use only an approved combination
of cutting attachment, deflector,
handle and harness. All parts must
be assembled properly and
securely.
– Check cutting attachment for
correct and secure assembly and
good condition.
– Check protective devices (e.g.
deflector for cutting attachment) for
damage or wear. Always replace
damaged parts. Never operate the
unit with a damaged deflector.
Clothing must be sturdy
but allow complete free-
dom of movement. Wear
snug-fitting clothing, an
overall and jacket combi-
nation, do not wear a
work coat.
Wear sturdy shoes with
non-slip soles.
To reduce the risk of eye
injuries, wear snug-fitting
safety glasses in accord-
ance with European
Standard EN 166. Make
sure the safety glasses
are a good fit.
Wear heavy-duty work
gloves made of durable
material (e.g. leather).

– Never attempt to modify the controls
or safety devices in any way.
– Keep the handles dry and clean –
free from oil and dirt – for safe
control of the power tool.
– Adjust harness and handle to suit
your height and reach. See chapter
on "Fitting the Harness".
To reduce the risk of accidents, do not
operate your power tool if it is damaged
or not properly assembled.
If you use a shoulder strap or full
harness: Practice removing and putting
down the machine as you would in an
emergency. To avoid damage, do not
throw the machine to the ground when
practicing.
See also notes on "Before Starting" in
the instruction manual of the
KombiEngine you are using.
Holding and Controlling the Power Tool
Always hold the power tool firmly with
both hands on the handles.
On units with a loop handle and barrier
bar, left hand on loop handle, right hand
on control handle, even if you are left-
handed.
Make sure you always have good
balance and secure footing.
During Operation
In the event of impending danger or in
an emergency, switch off the engine
immediately by moving the slide control
/ stop switch/button to 0 or STOP.
The cutting attachment may catch and
fling objects a great distance and cause
injury - therefore, do not allow any other
persons within a radius of 15 meters of
your own position. To reduce the risk of
damage to property, also maintain this
distance from other objects (vehicles,
windows). Even maintaining a distance
of 15 meters or more cannot exclude the
potential danger.
The correct engine idle speed is
important to ensure that the cutting
attachment stops rotating when you let
go of the throttle trigger. Check and
correct the idle speed setting regularly. If
the attachment still rotates when the
engine is idling, have your dealer check
your machine and make proper
adjustments or repairs – see
KombiEngine instruction manual.
Take special care in slippery conditions
(ice, wet ground, snow), on slopes or
uneven ground.
Watch out for obstacles: Roots and tree
stumps which could cause you to trip or
stumble.
Make sure you always have good
balance and secure footing.
Never operate your power tool with one
hand.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
To reduce the risk of accidents, take a
break in good time to avoid tiredness or
exhaustion.
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Stay alert so as not to endanger
others.
If your power tool is subjected to
unusually high loads for which it was not
designed (e.g. heavy impact or a fall),
always check that it is in good condition
before continuing work – see also
"Before Starting". Make sure the safety
devices are working properly. Do not
continue operating your power tool if it is
damaged. In case of doubt, consult your
servicing dealer.

Deflector may be
used with mowing
heads. Do not use
metal cutting
attachments – risk
of injury.
To reduce the risk
of injury from
thrown objects,
never operate the
unit without the
proper deflector for
the type of cutting
attachment being
used.
FSB-KM
English

Special care must be taken when
working in difficult, over-grown terrain.
When cutting high scrub, under bushes
and hedges: Keep cutting attachment at
a minimum height of 15 cm to avoid
harming small animals.
Check the cutting attachment at regular
short intervals during operation or
immediately if there is a noticeable
change in cutting behavior:
– Turn off the engine. Hold the unit
firmly and press the cutting
attachment into the ground to bring
it to a standstill.
– Check condition and tightness, look
for cracks.
– Replace damaged cutting
attachments immediately, even if
they have only superficial cracks.
Clean grass and plant residue off the
cutting attachment mounting at regular
intervals – remove any build up of
material from the cutting attachment and
deflector.
To reduce the risk of injury, shut off the
engine before changing the cutting
attachment.
After finishing work or before leaving the
unit unattended: Shut off the engine.
Never continue using or attempt to
repair damaged or cracked cutting
attachments.
This may cause parts of the cutting
attachment to come off and hit the
operator or bystanders at high speed
and result in serious or fatal injuries.
Use only the deflector with properly
mounted line limiting blade to ensure the
mowing lines are automatically trimmed
to the approved length.
To reduce the risk of injury, always turn
off the engine before adjusting the nylon
line of manually adjustable mowing
heads
Using the unit with over-long nylon
cutting lines reduces the motor's
operating speed. The clutch then slips
continuously and this causes
overheating and damage to important
components (e.g. clutch, polymer
housing components) – and this can
increase the risk of injury from the
cutting attachment rotating while the
engine is idling.
Maintenance and Repairs
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the KombiTool and
KombiEngine instruction manuals. Have
all other work performed by a servicing
dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer. STIHL dealers are
regularly given the opportunity to attend
training courses and are supplied with
the necessary technical information.
Only use high-quality replacement parts
in order to avoid the risk of accidents
and damage to the machine. If you have
any questions in this respect, consult a
servicing dealer.
STIHL recommends the use of genuine
STIHL replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
To reduce the risk of injury, always shut
off the engine before carrying out any
maintenance or repairs or cleaning the
machine.
Symbols on Deflectors
An arrow on the deflector (inside and
outside) shows the correct direction of
rotation of the cutting attachments.
Shoulder strap
The power tool may be used without a
shoulder strap. Shoulder strap and
carrying ring are special accessories.
Inspect the work area:
Stones, pieces of metal
or other solid objects may
be thrown more than 15
meters and cause per-
sonal injury or damage
the cutting attachment
and property (e.g. parked
vehicles, windows).
FSB-KM

N With the engine running, attach the
machine to the shoulder strap.
Mowing Head with Nylon Lines
Nylon line achieves a soft cut for edging
and trimming around fence posts, trees,
etc. – less risk of damaging tree bark.
WARNING
To reduce the risk of injury, never use
steel wire in place of the nylon cutting
line.
STIHL PolyCut 6-3 Mowing Head with
Polymer Blades
For mowing unobstructed edges of
meadows (without posts, fences, trees
or similar obstacles).
It is important to follow the maintenance
instructions for the Polycut mowing
head.
Check the wear limit marks!
Wear limit marks are integrated in the
base of the PolyCut.
Do not continue using the PolyCut 6-3 if
one of the circular holes (1; arrow)
becomes visible or if the projecting rim
(2; arrow) has worn away. Install a new
mowing head.

WARNING
If the wear limit marks are ignored, there
is a risk of the cutting tool shattering and
flying parts injuring the operator or
bystanders.
To reduce the risk of accidents from
shattered blades, avoid contact with
stones, metal and similar solid objects.
Check PolyCut blades for cracks at
regular intervals. If a crack is found in
one of the blades, always replace all the
blades.
